SPECIFICATION forming part of Letters Patent No. 645,349, dated March 13, 1900.

Application filed March 6, 1899. Serial No. 707,954. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH OONLEY, a citizen of the United States, residing at Mound City, in the county of Holt and State of Missouri, have invented new and useful Improvements in Refuse-Burners or Crematories for Burning Garbage, of which the following is a specification.

This invention relates to improvements in refuse-burners or crematories for burning garbage, the object of the invention being to provide a portable and knockdown crematory for incinerating garbage and like refuse which is constructed so as to be made up of few parts, the parts being readily separated one from the other and capable of being packed for transportation, so as to occupy but little space.

The refuse-burner orcrematory shown in the accompanying drawings is designed more particularly for camp uses, and with such an end in view the parts are made up of sheet metal, those parts of the sheet-metal plates which are subjected to direct contact with the flames being covered with sheets of asbestos, and in practice the upper grate upon which the refuse is first placed is made in the form of in the garbage may be evaporated from the solid parts, such parts being subsequently used as fuel.

The invention consistsin the novel features of construction, as will be hereinafter set forth,.and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is perspective view of a refuse-burner or garbage-crematory constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view, and Fig. 3 is a transverse section.

- nals formed at the ends of the upper gratebars, which journals extend through the bearings. The side plates have vertical flanges a, the edges of which abut when the furnace is set up. It will be noted that the flanges project at right angles to the plates and are provided with openings which register with openings in the adjacent flanges, so that the parts may be readily connected when the furnace is set up by the use of ordinary stovebolts. I

The ends of the vertical walls B B of the garbage-crematory have flanges which project in opposite directions, and to the outer or end flanges are attached the side walls A, so as to form a rectangular structure. The front wall Bis make up of two similar plates, each plate being of substantially the, same size as one of the side plates, and these front plates have therethrough three openings, the two upper openings being provided with doors of the usual type. The lower opening, leading into the ash-pit, may also be provided with a door, if desired.

The top plate of the fn rnace comprises four separable sections which are curved transversely, the outer edges having upturned flanges, and when these plates are connected they are adapted to fit within the side and end walls, resting upon projections or ledges carried by or attached to the upper plates of the side walls. The two rear plates used in the make-up of the top 0 have openings, above which are placed hoppers 0, so that the hoppers will be located near the center of the furnace, and the other plates have openings over which are placed stacks or chimneys 0 which are positioned adjacent to the corners near the front wall.

Bottom plates D D of sheet metal may be provided, if desirable, but in ordinary use the side walls may rest upon the ground.

Within the furnace is a longitudinal dividing-wall E, which may be of heavier metal than the side and top walls, and the upper edge of this longitudinal wall is provided with recesses, in which rest the inner journals of the upper grate-bars F F. The grate-bars F F may be of cast metal or stamped up of sheet metal and are concave in cross-section, so that when their concave portions are upward they form a series of pans or vessels which will receive the liquid portion of the garbage, so that it maybe evaporated from the solid parts. The grates F F have parallel sides and are provided at their ends with gudgeons, which project on a line with their upper edges, so that the grates will hang therefrom, and as the depth of the grates is considerably less than the width when one of the grates is turned the products of combustion from the fuel on the grate H will pass around the grate that has been turned from a horizontal to a vertical position. At a suitable distance from the front wall of the furnace-and attached to the longitudinal dividing-wall E is a vertical plate G, which forms the rear walls of the ash-pit and serves as a support for the rear ends of ordinary grate-bars H, said grate-bars being supported at their forward ends by the front walls. From the upper side of the vertical plate G, so as'to extend rear of the ashpits and incline upward therefrom, is a cor rugated plate I, to the rear end of which is secured a curved section 1, the rear end being attached by bolts to the rear walls of the furnace.

The vertical walls below the grates F F and above the grate-bars H H and the corrugated plate I are covered with asbestos or other suitable non-conducting material, so as to protect the side plates from direct contact with the flame, and the longitudinal wall E is similarly protected. The object of corrugating the plates 1 transversely is to form a series of recesses which will retain a certain amount of the fluids which may fall from the upper grates, and such fluids and ashes will serve to protect the plate from the direct contact of the flames.

It is desirable that the liquids which are present in the garbage should be disposed of, and I prefer to evaporate them, and with this end in View the furnace may have attached thereto above the grates F and to the exterior of the side walls receptacles K, which are bolted or otherwise attached to the side walls and are provided with valved conduits 7a, which lead into the furnace above the grates F, and these receptacles may also be provided with pipes it, so that steam may be led directly into the furnace from said receptacles.

4l5J-The receptacles K are of the shape shown and are provided with hinged covers.

For camp uses it is preferred that the garbage should be collected in garbage-receptacles such as'are shown in my patent dated March 21, 1899, as in such a receptacle the liquid parts of the garbage are separated from the solid matter, and said solid matter is passed into the furnace through the doors above the grate-bars F and also through the hoppers. Wood or other fuel is placed upon the lower grates, and when the fire is started the products of combustion will pass under and over the garbage, as indicated by the arrows on Fig. 2 of the drawings, and when the same is sufficiently dried one or more of the grates may be dumped, so that said dried garbage will serve as fuel for burning subsequent charges. As the garbage is heated the grease and other like material will be caught in the concave grate-bars and the liquid will be evaporated, so that the concave grates will not only serve as a series of evaporatingpans, but the liquid which they may contain will prevent the burning out of said grates. The fluids which have been separated from the garbage may be placed in receptacles K and fed into the furnace over the concave grates by the ways or pipes 70. ,Each of the grates F is provided with means for dumping them, one independent of the other, so that the required amount of garbage dried and heated may be dumped either upon the deflecting-plate or upon the grate H.

The metal plates constituting the sides, ends, top, and the division-wall may be completely covered on their inner sides with sheets of asbestos, which have an interposed wire netting or fabric, such sheets of fireproof material being attached to the plates by staples or in any other convenient manner. When the furnace is so constructed, the asbestos will prevent the metal plates buckling or getting out of shape and wilLretain the heat within the furnace.

If desirable, the furnace may be mounted on wheels, so that it can be readily moved from place to place and the parts being bolted together can be readily separated and packed or nested, so as to occupy a comparativelysmall space, which is a great advantage in a structure designed with the object in view.

With the furnace shown a comparativelysmall amount of wood or fuel is needed to dry out the first charge of garbage, and after the fire is started the garbage which is dried out serves as fuel for subsequent charges.

After the garbage in one of the grates F has been dried said grate can be dumped, and while maintained in a vertical position the products of combustion will pass around said grate between the grates adjacent thereto. Thus should it at any time be desired to use only a few of the grates those that are not in use may be placed in a vertical position, so that the products of combustion will pass entirely around those in use.

By duplicating the construction on each side of the center of the furnace the garbage may be fed into the same, so that what is deposited on one set of concave grate-bars or receptacles after having been dried out may be dumped on the grates beneath and used as fuel for a charge which may be subsequently placed on the concave grates. It is obvious that the products of combustion from the garbage on one of the sets of grates as it is being consumed will heat and dry out the garbage on the other set of concave grates, and by feeding the garbage alternately through it' he differenthoppers the garbage is used as uel.

This crematory for garbage has been in practical use and has proved to be an efiective way of disposing in a healthful manner of large quantities of garbage and camp offal.

I claim- 1. In a refuse-burner or garbage-crematory constructed substantially as shown, of two se ries of garbage-receptacles within the cren1atory, hoppers positioned above said receptacle, and tanks attached to the sides of the crematory and provided with pipes for conveying fluid from the tanks to the garbagereceptacles, for the purpose set forth.

2. In a refuse-burner or garbage-crematory, a series of garbage-receptacles, hoppers positioned above the same, tanks supported above the level of the receptacles, substantially as sh0wn,whereby the garbage-receptacles serve to receive the solid garbage from the hoppers and the liquid refuse from the tanks.

3. In a refuse-burner or garbage-crematory, the combination with a furnace having a series of concavo-oonvex garbage-receptacles, together with hoppers carried by the top of the crematory and positioned over the garbage-receptacles, whereby the solid garbage may be fed onto the said receptacles from the hoppers, of fluid-receptacles attached to the exterior vertical walls of the furnace, said receptacles having means for conveying fluid therefrom to the garbage receptacles, substantially as shown.

4. In arefuse-burner, the combination with '2 the sheet-metal side walls and top, of a ver tical longitudinal wall which divides the lower portion of the structure into two sections, grate-bars, ash-pits, a pair of transverselycorrugated plates which extend from the ashpits rearward and upward, longitudinal series of concavo-convex garbage-receptacles which are of a greater width than depth journaled upon the dividing-wall and in the sidewalls, hoppers carried by the top wall of the furnace and positioned above the garbage-receptacle, and liquid-receiving tanks attached to the side walls and provided with pipes which lead from said tanks through the side walls to the garbage-receptacles,substantially as shown and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.

JOSEPH CONLEY.
